Engineers in France have started work to drain an immense lake that has built up under an Alpine glacier on Mont Blanc, an attempt to prevent a repeat of a flood that killed 175 people more than 100 years ago.
Specialists are drilling into the glacier as part of preparations to slowly pump out the 65,000 cubic meters (2,275,000 cubic feet) of liquid believed trapped beneath the Tete Rousse glacier, the mayor of the Alpine town of Saint-Gervais-les-Bains said Wednesday. The amount of water is equivalent to about 26 Olympic-sized swimming pools.
